Abstract

PROBLEM TO BE SOLVED: To form precisely shaped protrusions and thereby enhancing the antiskid effect of a mat by constituting a roll of a core with numerous recessed grooves formed along the outer periphery and a porous sleeve fitted onto the outside of the core and further making the pores of the porous sleeve communicate with the recessed grooves of the core. SOLUTION: The roll 3 is constituted of a core 4 and a porous sleeve 5 fitted onto the outside of the core 4. The core 4 is hollow so that a cooling water is made to flow through internally and has numerous recessed grooves 7 formed along the outer periphery. The porous sleeve 5 has numerous through holes 6, each consisting of a funnel-shaped part outside and a straight cylinder part inside. The recessed grooves 7 of the core 4 are arranged at a smaller interval than the innermost dia. of the holes 6. A heat-softened synthetic resin sheet 1 is fed into a space between the roll 3 and a backup roll 9 to form protrusions 2 on the back face of the sheet 1. During forming the protrusions 2, the protrusions 2 are precisely formed without receiving an air interference by evacuating air from the holes 6 to the outside through the recessed grooves 7.

In the present invention, when the synthetic resin sheet (1) in the heat-softened state is pressed by the roll (3), the roll (3)
The softened synthetic resin product of the sheet (1) enters into the hole (6) of the portion of the porous outer cylinder (5) of (3) which is in pressure contact with the sheet (1). The air in the hole (6) is the core of the roll (3).
The air is naturally exhausted from the open holes on both sides of the hole (6) to the outside through the concave groove (7) of (4). Therefore, in the present invention, the projections on the sheet surface are formed into an accurate shape without being interfered by the air in the holes of the roll. In particular, in the present invention, since the air in the hole of the roll is naturally exhausted, the projection shape becomes accurate. If the air in the hole of the roll is evacuated, the heat-softened synthetic resin overflows from the back of the hole and generates burrs.
